Setting TPM_CHIP_FLAG_SUSPENDED in the end of tpm_pm_suspend() can be racy
according, as this leaves window for tpm_hwrng_read() to be called while
the operation is in progress. The recent bug report gives also evidence of
this behaviour.
Aadress this by locking the TPM chip before checking any chip->flags both
in tpm_pm_suspend() and tpm_hwrng_read(). Move TPM_CHIP_FLAG_SUSPENDED
check inside tpm_get_random() so that it will be always checked only when
the lock is reserved.

XDP and XDP socket require extra SQ/RQ/CQs. Most of these resources
are dynamically created: no XDP program loaded, no resources are
created. One exception is the SQ/CQ created for XDP_REDRIECT, used
for other netdev to forward packet to mlx5 for transmit. The patch
disables creation of SQ and CQ used for egress XDP_REDIRECT, by
checking whether ndo_xdp_xmit is set or not.
For netdev without XDP support such as non-uplink representor, this
saves around 0.35MB of memory, per representor netdevice per channel.

Dynamically allocating xdpsq, used by egress side XDP_REDIRECT.
mlx5 has multiple XDP sqs. Under struct mlx5e_channel:
1. rx_xdpsq: used for XDP_TX, an XDP prog handles the rx packet and
transmits using the same queue as rx.
2. xdpsq: used by egress side XDP_REDIRECT. This is for another interface
to redirect packet to the mlx5 interface, using ndo_xdp_xmit .
3. xsksq: used by XSK. XSK has its own dedicated channel, and it also
has resources of 1 and 2.
The patch changes only the 2. xdpsq.

The first approach was flawed, because there are situations where the
esw mode change fails, leaving the qos domain as NULL. Various calls
into the QoS infra then trigger a NULL pointer access and unhappiness.
Improve that by a combination of:
- Allocating the QoS domain on esw init and cleaning it up on teardown.
- Refactoring mode change to only call qos domain init but not cleanup.
- Making qos domain init idempotent - not change anything if nothing
needs changing.
Together, these should guarantee that, as long as the memory allocations
succeed, there should always be a valid qos domain until the esw
cleanup, no matter what mode changes happen (or failures thereof).

net_dim() is currently passed a struct dim_sample argument by value.
struct dim_sample is 24 bytes. Since this is greater 16 bytes, x86-64
passes it on the stack. All callers have already initialized dim_sample
on the stack, so passing it by value requires pushing a duplicated copy
to the stack. Either witing to the stack and immediately reading it, or
perhaps dereferencing addresses relative to the stack pointer in a chain
of push instructions, seems to perform quite poorly.
In a heavy TCP workload, mlx5e_handle_rx_dim() consumes 3% of CPU time,
94% of which is attributed to the first push instruction to copy
dim_sample on the stack for the call to net_dim():
// Call ktime_get()
0.26 |4ead2: call 4ead7 <mlx5e_handle_rx_dim+0x47>
// Pass the address of struct dim in %rdi

Export the pwm_get_state_hw() function. This is useful in cases where
we want to know what the hardware is actually doing, rather than what
what we requested it should do.
Locking had to be rearranged to ensure that the chip is still
operational before trying to access ops now that this can be called
from outside the pwm core.

Simplify Tx napi logic relying just on the packet index provided by
completion queue indicating the completed packet that can be removed
from the Tx DMA ring.

In order to avoid any possible race, read completion queue head and
pending entry in airoha_qdma_tx_napi_poll routine instead of doing it in
airoha_irq_handler. Remove unused airoha_tx_irq_queue unused fields.
